The Pay It Forward Challenge

Jennifer Sacalis wants to thank a military wife for supporting a serviceman in Iraq. She finds Kathy, whose husband has been serving in Iraq for 15 months.

Jennifer buys a spa package for Kathy and a gift certificate for a dinner with her children at a local steak house. She also gives Kathy money for Christmas presents and routine expenses.

"I think I made Kathy's day," Jennifer says once her challenge is complete. "I just wanted to touch her and raise her sprits, and I think I did … I just wanted to let her know that she's not alone."
